soar AND warns MIXER.

Original No. 1,486,100, dated Our said invention relates to apparatus for use m obtaining a soap solution, or a mix- I hire of soap and water, by directing a supply of water into a supply of soap so that the 5 water will act to dissolve the soap andbe v come mixed therewith to form a solution, and 1t conslsts in a construction of such an apparatus and an arrangement of its parts whereby such solution may be readily and rapidly secured. 3 While said apparatus is with other materials for other'pur1)oses as .our invent-ion to provide such an apparatus by which theproportions of soap and water may be readily varied and positively. regulated so as to produce, a solution of a predetermined strength, or predetermined soap content, such as may be adapted for the particular purpose for which the solution produced is intended. I Another object of the invention is to pro r-vide such an apparatus by the use of which the soap will be thoroughly dissolved in the water before reaching the point of use, so

so that no small undissolved particles of the I soap .will be present in the solution, thusavoidingt-he disadvantages common to other devices of this character. 1 v

This and vvarious other objects and adv-anastages, which will be appreciated by those skilled in the art whereby an apparatus of the character described is provided which is adapted for ready connection with a source of supply of water, of a comparatively inv4o expensive construction and efficient in operation, characterize our said invention.

Referring to the accompanying drawings, which are made a part'hereofand on which i similar reference characters indicate similar Figure. 1 1s a vertical section on line 11 of Figure 2 through an apparatus of the character described-embodymg our said invention, and

.so that the rotation of the plate plan of the "valve used- March 4, 1924, Seria1 No. 580,868, filed August 10, 1922. Application for reissue filed July 3, 1924. Serial No. 724,055,

dic ates the inlet neck of the apparatus which I may be, secured to a-wat'er pipe 32 having i a valve 2 for controlling the supply of water to the upper end of the apparatus. The upper end of the casing forms a chamber 3 in.

which is interposed a plate 6 perforated for thepassage of water. Adjacent the plate 6' is-mounted a plate or valve 5 of appropriate form to regulate the flow of Water. In the forations adapted, when turned to proper 'form shown it consists of a disk having per- .1

position, to register with those of plate 6.

Such a valve, however, is not essential to the leading function of the apparatus but only to its use when the strength of the best shown in Figure 2 the perforation in the two plates are of two sizes, the upper plate having small perforations 16 and large perforations 17 arranged. near its outer edge while the lower plate has a smaller number of perforations all ofwhich are large. The

u-pper'plate also has largeperforations 14 and smalllperforations 15 arranged in a circle near the middleof the plate and the lower plate has a smaller number of perforations to register with perforations 14 and-15,

those in the bottom plate being larger than.

those of either setin the corresponding circle on the upper plate for the purpose among others of insuring registration with the smaller passages in the upper plate. In the present embodiment of the invention the large and small perforations are shown as arranged alternately in the respective circles may vary the flow of the water by regist ring-large perforations in the one plate with either largeor small perforations in the other plate,

or more or less area of-the perforations in Y the respective plates; Other forms of valve 4 devices-adapted to accomplish the regulation of flow will readily suggest themselves to those skilled in the art and we therefore de- 1 sipe to have it understood that we do not.

' limit our invention to the particular formshown, ortothe arrangement of the perforations, as any suitable arrangement, other than that shown, may be employed.

The late 5 has aboss4 onits in whic is a transverse notch 25. stem 13 has a fin 24 fitting in the notch and up' r side Tl idvalve' frictional contact. The upper end 23 of the valve stem is formed to be engaged by a key, or other apprcipriate operating device. It will be understood, of course, that any .appropriate means for operating the valve and securing it in any desired position may be used, that shown being only one means for such purpose, which will readily suggest themselves to one skilled in the art.

The main chamber 7 is of any preferred form orsize, here shown as cylindrical. Mounted therein is a soap holder 8 consistmg essentially of two parts, here shown with a cylindrical body spaced from and concentric with the casing 7 though it may be of any other desired form and mayor may not be concentric according to the arrangement of the valve above it and other considerations. The body of said soap holder has-a number of perforations 9 through its walls arranged at different heights about the same. Its bottom may or may not have perforations and is shown as resting on lugs 22. which space it from the bottom of the mixing tank or chamber and which are spaced from each other. The upper end of the soap holder is provided with atop or cap 11, in this isstancehaving the shape of a frustum of a cone. 'Said cap has a flange 30 which fits over the'top of the body and is open at the upperend at 21 underneath the inner circle or any predetermined number of holes in the plate 6. An outlet 19 adapted for connection with a discharge nozzle, or a pipe to conduct the soap solution to the point of use, is provided in the bottom of chamber 7.

The operation. of said invention is as follows: The apparatus is installed by being attached as indicated in Figure 1 to a water supply pipe 32. The soap container 8 is filled, or partially filled, with soap of any desired character, either solid or semi-solid in its nature. The cap or cover 11 is adjusted to positionand the water turned on by means of the valve '2. The water going through the perforations in plate 6'within the circle of'the opening21 passesinto the top of the container, flows over the top of the soap or through the soap, forming a soap solution which flows through perforations 9 into the space between the soap container and the walls of the chamber 7, the solution passing down and out through outlet 19 which is connected to a pipe or nozzle by which the solution is conducted to the point where it is to be useiL .By the -use of the valve 5 the vo1+ ume of water passing into the soap container may be regulated as has been heretofore de scribed so that a greater or less soap content will be contained in the solution passing out from the outlet. It is very desirable in many instances to have such means of regulating the soap content as different strengths of solution are desirable for clifi'erent uses, and by this means just the character of solution required in this,respect may be provided for every purpose. The water flowing through the outer circle or line of perforations, flows upon the outer surface of the inclined top 11 and passes down over the outer wall of the soap container, keeping the soap container washed free of soap content and adding water to the soap solution as may be required. If it appears desirable to provide for a supply of clear water; e. g., for rinsing, the perforations may be so arranged that the valve 5 can beadjusted so as to close the perforations above the open top of the container and leave open only the openings in the outer circle so that water will fall only upon the outside of the soap container and fiow down and out through the outlet 19 without mingling with the soap.

By this means an apparatus of the character described is provided which is capable of a variety of uses and may be regulated to produce just the strength of solution desired for any particular use.

One of the main advantages of my device is that by its use a solution can be made which will be absolutely uniform for all practical purposes from the beginning of the operation until practically the very last of the cake or mass of soap is dissolved. Among other reasons this is true because the Water falls in uniform volume and at uniform pressure (except as the pressure is adjusted by valves 2 and 5 to change the soapiness or soap content of the solution), and falls on a surface of uniform area at all times. The

water or more properly the solution of soap,-

and water flows off at once so that the mass of soap is neither softened by water standing thereon nor does a blanket of water protect the soap against the action of the water, as would be the case if the perforations did not extend all the way down the sides The inventors are aware of Patent No. 623,851, to Van Riper and do not claim the invention there disclosed butthey do claim to be the first to cause water to flow over a solid (continuous) block or mass of either hard, soft or semi-solid soap in a maimer to produce a uniform solution, instead of percolating through a granular mass of material as in the patent mentioned.

It will be understood, of course, that the v apparatus as illustrated is only of a form which has been found desirable in actual use but may be varied in detail in many respects without departing from the spirit or purl perforations laterally spaced from said open pose of our invention. For example,the soa container-may be woven wire or other reticulated material and water may be diverted to flow outside the soap container by other means than the inclined top and the open top of the container may be covered ing water into fine streams or spray.
